As Greenland’s Ice Melts, Glacial Sand Deposits May Offer a Welcome Economic Opportunity – Columbia Climate School

Greenland’s glaciers grind rock into a fine powder that discolors meltwater and often makes beautiful patterns as it mixes with seawater.(courtesy of NASA Earth Observatory, by Joshua Stevens, using Landsat data from the U.S. Geological Survey. Public Domain).

Greenland’s ice sheet is losing 280 billion tons of mass per year, and some models suggest that its glaciers may be melting up to 100 times faster than expected. But flowing off those glaciers comes a potential economic boom: sand. Each season, millions of tons of sediment flow from melting glaciers into the ocean, adding landmass to the largest island in the world. According to a research paper published in Nature last fall, three out of four Greenlanders support extracting and exporting sand — so long as they’re the ones in charge of managing the resource…

The Foul Chartreuse Sea – Yale Climate Connections

Blooming Cyanobacteria! (by Charos Pix CC BY-NC-ND 2.0 via Flickr).

Researchers in Kotzebue, Alaska, are investigating why their town is increasingly playing host to harmful cyanobacteria.

Dead fish were everywhere, speckling the beach near town and extending onto the surrounding coastline. The sheer magnitude of the October 2021 die-off, when hundreds, possibly thousands, of herring washed up, is what sticks in the minds of the residents of Kotzebue, Alaska. Fish were “literally all over the beaches,” says Bob Schaeffer, a fisherman and elder from the Qikiqtaġruŋmiut tribe…

Barcelona’s beaches could vanish as authorities abandon ‘enhancement’ – the Guardian

For the 1992 Olympic Games, Barcelona rediscovered the sea. It beefed up its beachfront using thousands of tons of sand, and the area is now packed with tourists and lined with beach bars. Barcelona’s beach may be partly artificial, but it’s big business. The way things are going, however, soon there won’t be any beach at all. Across Catalonia, rising sea levels and winter storms are eating away at the coastline…

Lost Lands: Mining the Mekong – the South China Morning Post Films

Cambodia’s appetite for sand has exploded as construction continues to fuel economic growth in the capital Phnom Penh. But as the thirst for sand grows, so does the uncertainty over the future of the river. Two families who rely on the river for a living share their stories of how sand dredging is causing pain and concerns for the future.

The Earth Transformed: An Untold History – Reviewed in the Atlantic

In his sweeping new book, Peter Frankopan looks at how the climate has changed human society—and how we have changed the climate.
Does climate change directly influence the weather we experience? Until recently—for the past 40 years or so—that question has followed nearly every major hurricane or flood, every record snowfall or heat wave. In some people, it provokes instant denial, often political or economic, often rooted in prideful ignorance…

Giant blobs of seaweed are hitting Florida. That’s when the real problem begins – NPR

Sargassum Seaweed, Sunny Isles, Florida (by Jimmy Baikovicius CC BY-SA 2.0 via Flickr).

It used to be that the conversation around subtropical marine life centered on declines: the death of coral beds, the diminishing variety of seagrasses, the disappearance of fish. But for now, it’s an overabundance that’s hard to miss. From Montego to Miami, an influx of algae called sargassum is leaving stinky brown carpets over what was once prime tourist sand. It’s the most sargassum researchers have tracked this early in the year. Deciding what to do with it is proving more challenging the more we learn about it — and inspiring some entrepreneurs to rethink removing sargassum altogether…

The Jury is Out: Has the Supreme Court Just Shredded the Environmental Policymaking Safety Net?

Equal Justice Under Law - the pediment of the Supreme Court bulding, Washington, DC (by Thomas Hawk CC BY-NC 2.0 via Flickr).

Remember what it was like as a kid when a grownup told you “Because I said so”?

Well, a newly constituted majority of the U.S. Supreme Court has recently flexed its ideological muscle, upending 50 years of precedent guiding its decisions, and basically told us “Because I said so.”

This quiet revolution by an activist majority, deciding cases based on primarily political grounds rather than on the constraints of facts and legal precedent, will have grave impact on environmental policymaking – as well civil rights, healthcare, safety, education, elections, technology, finance, and economics…

Yet Another Problem With Recycling: It Spews Microplastics – Wired Magazine

An alarming new study has found that even when plastic makes it to a recycling center, it can still end up splintering into smaller bits that contaminate the air and water. This pilot study focused on a single new facility where plastics are sorted, shredded, and melted down into pellets. Along the way, the plastic is washed several times, sloughing off microplastic particles—fragments smaller than 5 millimeters—into the plant’s wastewater…
